Galvanic isolations
The KS 816 galvanic isolations are shown below:
Identical block shading means that the blocks are galvanically connected. (All in-
puts are galvanically connected.)
4.3 Power supply
KS 816 is designed for 24V DC nominal supply voltage, range 18V to 30V, 5%
ripple. The supply voltage must meet the conditions for protective low voltage
(SELV) to CEI 364-4-41 [VDE 0100-410].
Power supply load by one KS 816: approx. 5 W
Energization is via terminals 7 (+) and 8 (-) of connector X3.
.
4.4 Fuses
Each unit must be protected with a separate 2A slow-blowing fuse (fitted in the ter-
minal). We recommend using terminals with built-in fuses.
Unless LED "PWR" is lit with the supply voltage applied (check fuse and polarity),
the unit is defective and must be returned to the manufacturer.
